A PMMC instrument has a 0.12T magnetic flux density in its air gaps. The coil dimensions are D = 1.5 cm and l =2.25 cm. Determine the number of coil turns required to give a torque of 4.5 μN-m when the coil current is 100μA. Td = NBldI N = Td / BldI = 4.5 x 10-6 / (0.12 x 2.25 x 10-2 x 1.5 x 10-2 x 100 x 10-6) N = 1111

What is the use of swamping resistor? Swamping resistor is connected in series with meter resistance to reduce the error caused by temperature rise (i.e. temperature error). Swamping resistance to meter resistance ratio should be high
